Background: Total hip arthroplasty (THA) is an effective treatment for advanced osteonecrosis of the femoral head, which can significantly relieve pain and improve patients' quality of life. Robotic-assisted THA enhances the accuracy and stability of THA surgery and achieves better clinical outcomes than manual THA.
Case summary: We report the clinical outcomes of robotic-assisted THA and manual THA in the same patient with osteonecrosis of the femoral head. A 49-year-old male patient attended our hospital due to more than 3 years of pain in both hip joints. The left hip was treated with robotic-assisted THA. The patient underwent manual THA of the right hip 3 mo after robotic-assisted THA. We obtained postoperative radiograph parameters, Harris hip score and forgotten joint score of the patient 1 year after surgery.
Conclusion: Compared with manual THA, the patient's left hip felt better 1 year after robotic-assisted THA. Robotic-assisted THA resulted in a better Harris hip score and forgotten joint score than manual THA in the same patient with osteonecrosis of the femoral head.
